IMPROVED LUBRICATlNG COWlPOUND.

Specification forming part of Letters Patent No. 9?,335. dated November 230, 1869.

' To all whom it may concern:

Be it known that I, W. N. ABBOTT, or the State of Massachusetts, have invented certain Improvements in Composition of Matter for Lubricating Machinery, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to composition of matter for the purpose of producing a lubricant for machinery and consists, first, in mixing a certain quantity of soap-stone, magnesia, lime, and water, and then adding about an equal quantity of any animalor vegetable oil or grease, as hereinafter explained.

In making my composition for a lubricant I take five (5) pounds of soap-stone, five (5) pounds of magnesia, and a half-bushel of lime, and dissolve them in about forty (40) gallons of water, and, when completely dissolved or mixed, I add about an equal quan- .tity, by measure, of any animal or vegetable oil, or of any grease or fatty matterreduced to the consistency of oil, and then thoroughly mix the whole in any convenientmanner."

A smaller or larger quantity of the mixture may be made by taking any fractional parts of the above proportion of ingredients, or any multiples of the same, and mixing them in a similar manner.

While the proportions above given are found to give the most desirable results,yet the quantity of each ingredient maybe somewhat varied, and still a very useful product'be obtained.

This mixture I have discovered by long and continued use to be both serviceable and durable. It answers a better purpose than pure oil or grease, and is cheaper and safer. The ingredients are few, cheap, and readily obtained. The great quantity of earthy matter and water in the composition serves to protect it from" fire, and thus renders its use safe in the presence of that element.

Having thus described my composition, What I claim is A lubricant for machinery composed of the ingredients in the proportions and manner substantially as herein described.

W. N. ABBOTT.
